What is Microsoft Word? Features, Uses, and Free Access

What is Microsoft Word?

Microsoft Word is a word processor — software for writing, formatting, editing, and sharing text documents. It has been the standard tool for business and academic writing since the 1990s, and its file format, .docx, is the default way documents are exchanged in most workplaces worldwide.

You can use Word free in a web browser with a Microsoft account. The full desktop version comes with a Microsoft 365 subscription, from $9.99 a month, or as a one-time purchase.

What Word actually does

At its simplest, Word is for producing a document that looks the way you intend and can be read by someone else without anything breaking. That covers more ground than it sounds like.

Writing and editing. Typing, revising, spell and grammar checking, word counts, find and replace, comments, and tracked changes so several people can revise the same document while keeping a record of who changed what.

Formatting and layout. Fonts, headings, paragraph spacing, margins, columns, page numbers, headers and footers, bullet and numbered lists, tables, images, and captions. This is where Word separates itself from simpler tools — long structured documents with consistent styling are what it is built for.

Structure for long documents. Heading styles that generate an automatic table of contents, cross-references, footnotes and endnotes, indexes, and section breaks with independent formatting. Anyone writing a thesis, a report, or a manual relies on these whether they realize it or not.

Collaboration. Documents saved to OneDrive can be edited by several people at once, with changes appearing live and version history retained.

Output. Printing, exporting to PDF, and mail merge — generating hundreds of personalized letters, labels, or emails from a spreadsheet of names.

What people use Word for

The honest answer is almost any document that is mostly words:

1. Business letters, memos, and internal communications
2. Reports, proposals, and business cases
3. CVs, cover letters, and job applications
4. Academic essays, dissertations, and research papers
5. Contracts and formal agreements, usually with tracked changes during negotiation
6. Meeting minutes and notes
7. Newsletters, flyers, and simple marketing material
8. Manuals, procedures, and documentation
9. Forms, invoices, and certificates from templates
10. Mail merges for bulk correspondence

If a document needs to be printed, signed, formally reviewed, or read by someone who expects a familiar file, Word is usually the path of least resistance.

Is Microsoft Word free?

Partly, and the answer catches people out.

Word for the web is free. With a free Microsoft account you get browser-based Word, Excel, and PowerPoint, along with 5 GB of OneDrive storage. There is no trial period and no card required. The main constraint is that files are saved in and shared from OneDrive.

The web version handles the great majority of everyday writing. It is genuinely capable — not a crippled demo.

The desktop apps are paid. The full Windows and Mac versions, with the deeper layout and reference features, come with a Microsoft 365 subscription or a one-time purchase.

Mobile apps. Word is available on iOS and Android. Basic editing is free with a Microsoft account; some features require a subscription.

What it costs in 2026

Prices are US dollars and current as of September 2026.

Subscriptions for home use:

PlanMonthlyAnnualPeopleCloud storage

Microsoft 365 Personal$9.99$99.991 (up to 5 devices)1 TBMicrosoft 365 Family$12.99$129.991–6Up to 6 TBMicrosoft 365 Premium$19.99$199.991–6Up to 6 TB

The Premium tier is newer, and most explainers on this topic have not caught up with it. It offers more extensive Copilot usage, including agentic capabilities. Note that on the Family plan, Copilot access goes to the subscription owner rather than to all six people.

One-time purchase: Office Home 2024 costs $179.99 for one PC or Mac. No cloud storage, no Copilot, and no new features — it stays as it is. Worth it if you keep software for many years and want no recurring cost; poor value if you upgrade regularly.

Business plans run from $5.40 to $32.00 per user per month depending on the tier and whether Teams is included. Note that Copilot is now bundled into the Business Standard and Premium tiers and their pricing, rather than sold as a separate add-on — a change from earlier years that older comparisons will get wrong.

Word, Office, and Microsoft 365: the naming, correctly

The branding has shifted, and a lot of published explanations are out of date.

Microsoft 365 is the subscription brand covering Word, Excel, PowerPoint, Outlook, OneDrive and more.

Microsoft Office is effectively retired as a consumer brand. The name survives only in the one-time-purchase products.

Office 2024 is the current perpetual version. There is no Office 2026 and no Office 2027 — Microsoft’s own update documentation covers only the 2024 releases, so treat any claim otherwise as unverified.

One quirk that confuses people: Word’s internal version number is 16.0, and has been since 2016. A “Word 16” reference does not mean an old copy.

There has also been movement in mobile and web branding — the Microsoft 365 hub app was renamed the Microsoft 365 Copilot app in January 2025, with the web endpoint moving accordingly. Microsoft’s branding in this area is genuinely confusing at present, so check what you are buying rather than assuming from a name.

Copilot in Word

Copilot is Microsoft’s AI assistant, built into Word for subscribers on eligible plans. Microsoft describes it in four functions:

1. Create — draft from a prompt, an outline, notes, or a referenced file
2. Refine — rewrite selected text, change tone, or tighten wording
3. Comprehend — summarize a document, ask questions about it, or test an argument
4. Collaborate — work inside the original file with changes you can review before accepting

It is available in Word for Microsoft 365, Word for Mac, Word for iPad, and Word for the web, and requires an eligible subscription or a Copilot license. Copilot supports fewer languages than the Word interface itself, which matters if you work in a less widely supported language.

One correction worth making: Microsoft’s documentation does not state that Copilot requires files be saved to OneDrive, despite that claim circulating widely.

A brief history

Word is older than most of the people using it.

1983 — Released on 25 October as Multi-Tool Word, for Xenix and MS-DOS. 1985 — First Macintosh version, which established Word’s reputation. 1989 — Word for Windows 1.0, the version that began its rise to dominance. 1990s — Word 95 and Word 97 made it the default in business, largely through Office bundling. 2007 — Word 2007 introduced the Ribbon interface and made .docx the default format. This is the single most consequential release: the Ribbon still shapes the interface, and .docx became the global standard for document exchange. 2013 onward — The shift to subscription with Microsoft 365, real-time co-authoring from 2014, Read Aloud and Immersive Reader, text prediction, and Copilot from 2023.

A small correction on a point often stated wrongly: Word 2003 shipped an XML format called WordML, but .docx and Office Open XML became the default in Word 2007, not 2003. The two get conflated constantly.

Word compared with the alternatives

Google Docs is free, browser-first, and better at frictionless real-time collaboration and version history. Word is stronger on long-document layout, typography, and reference features — tables of contents, cross-references, indexes. If your documents are short and collaborative, Docs is often the better tool. If they are long and structured, Word is.

LibreOffice Writer is free, open source, and installs locally. Version 26.8 arrived on 28 August 2026, and its positioning is interesting for 2026: the project explicitly markets professional typography, deep support for the world’s writing systems, and no artificial intelligence. It is deliberately local-first, with no cloud dependency and no AI features. For anyone who wants a capable word processor with nothing phoning home, that is a genuine selling point rather than a limitation. It supports 120 languages and now offers a ribbon-style interface option.

WPS Office offers a free tier with strong .docx compatibility and good mobile support, funded by advertising on the free tier.

Apple Pages comes free on Mac, iPad, and iPhone, and is strong on design-led documents, weaker on business-standard compatibility.

The practical reason most workplaces stay on Word is not features — it is that .docx is what everyone sends and expects back, and formatting fidelity when a document passes through several hands still favors the application that defines the format.

Getting better at Word

Most people use a small fraction of Word and do the rest by hand. Three habits that save the most time:

Use styles rather than manual formatting. Applying Heading 1 and Heading 2 instead of making text big and bold gives you a navigation pane, an automatic table of contents, and the ability to restyle a hundred-page document in one action.

Learn tracked changes and comments properly. In any workplace where documents get reviewed, this is the difference between a clean review cycle and a mess of conflicting versions.

Learn mail merge once. It converts a day of copy-paste into a few minutes, and almost nobody outside administrative roles knows it exists.

Is Google Docs better than Microsoft Word? It depends on the document. Docs is better for short collaborative documents and costs nothing. Word is better for long structured documents needing tables of contents, cross-references, and precise layout. Most organizations use Word because .docx is the exchange standard.

What does Copilot do in Word? Four things, in Microsoft’s framing: drafts content from a prompt or a reference file, rewrites and adjusts tone, summarizes and answers questions about a document, and makes reviewable changes in the original file. It requires an eligible subscription or Copilot license.
